used for driving; adrill bit in-well drilling,

or for driving a rotary brush designed for cleaning. boiler fines, and forother similar purposes. I

With the-above andother objects in view, this inventionlias particular relation to certainnovel featuresof construction, operation and arrangement of parts, an example of which is given in this specification and illiistrated in the accompanying drawings, 'wherein':

Figure 1 shows a vertical sectional view at the motor, as adapted 'for use in drivinga the like.

Figure 2' shows transverse sectional view thereof, taken on the line, 2-2 of Figure 1.

Figure 3 shows a vertical sectional view of a type of motor adapt-ed for use for the purpose of driving a drill bit in the process of well drilling.

Figure 4: shows a transverse sectional view taken on the line 47 of Figure 3.

Figure 5 shows a cross sectional view, taken on the line 55 of Figure 3.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures,the numeral 1 designates the motor housing which is preferably formed of two sections, screwed together. One end of this housing is reduced forming a sleeve as 2, and threaded into the other end of the housing there is a pressure line 3. Around the reduced portion 2 the housing has the spaced, arcuate discharge ports 4, and anchored to this end of the housing there is the cylindrical casing 5, having the side inlets as 6. This casing is concentric with, and spaced from the housing forming the annular pressure chamber 7. Within the casing there is a suitablerotor 8, formed with radiating blades 9, and mounted on the drive shaft 10. The casing .5 is closed, at one end, by the end screw cap 11 and its other end is formed with a spider 12 which forms a bearing against the adjacent end of the; housing. The spider 12 hassuitable outlet ports for the pressure fluid.

The'sliaft 10 is mounted to rotate onsuit able anti-friction bearings as 13, 18in the end cap 11 and-sleeve 2, respectively. The

free end of the shaft 10 has a rotary brush 14 fined thereon; This brush may be of any conventional construction. As shownit isvformed'of a plurality of discs, clamped to=- getheron the-shaft byethe clamp nut 15.

Stiff steel wires 16' are clamped between these discs, with their showin The fluid such as air or steam is admitted;

under pressure, througlrthe pipe 3 into the chamber 7, andpasses through the ports 6 and 1ts impact against the blades 9 turns the.

rotor 8 and the brush carriedby the shaft 10, the fluid escaping through the discharge ports 4. o In using this type of the device" as a flue cleaner, the pressure pipe niay'be. connectedto a flQXlblB pressure line and usedas a handle for inanipulating: the device.

In the form shown in Figure 3,- the screw cap'll of the casing has a central sleeve 17 into which a water line 18 is threaded, and a water conduit 19 leads down from said line 18, through the rotor shaft 10. lower end of the shaft 10 has a drill bit 20, of any desired construction, attached thereto, and provided with side water ports, as 21, 21. Water passes down through the water pipe 18, and on down through the water course 19 and out through the ports 21, and is thus supplied to "the bit to carry away the cuttings. In other respects this form of device is similar in construction and operation to the form shown in Figure 1.

That I claim is 1. A motor including a housing, a casing fixed. within the housing and spaced therefrom forming a pressure chamber therebetween, said casing having an inlet port leading through the casing wall from said chamber and an outlet leading from within said casing through the housing, a drive shaft rotatably mounted in the housing and easing, a rotor fixed on said shaft and located within the casing, and a pipe to which the motor is attached, said'pipe communicating with said chamber and forming means for com ducting motive fluid thereto and for suspending the motor.

2. A motor including a housing, a casing fixed therein at one end and having its other end free,.said casing being spaced from ends projectingas The the housing forming a pressure chamber therebetween, said casing being provided with an inlet port and an outlet port which leads out through the housing, a rotor mounted in the casing, a shaft rotatably mounted in the housing and fixed to the rotor, a pressure line entering said chamber, the outer end of said shaft having tool-attaching means thereon, said rotor and shaft having a water conduit therethrough with discharge ports on the sides of the shaft, and a water line secured to the casing in communication with said conduit.

3. A motor including a housing, a fluid pressure line entering the housing, 1. rotor formed with radiating blades rotatably mounted in the housing, a shaftfixed to the rotor and having a bearing in the housing, a casing within the housing, and enclosing said rotor and provided with a fluid inlet and outlet disposed to direct the fluid current against said rotor blades to rotate the rotor, the outer end of said shaft having tool-attaching means thereon, said fluid pressure line forming means for suspending the device. 7

4. A device of the character described including a housing, one end of which is provided with outlet ports, a casing within the housing which surrounds said ports and one end of which is fixed to the corresponding end of the housing and whose other end is free, the free portion of said casing being spaced from the housing to form a pressure chamber therein, a removable cap closing the free end of the casing, a shaft having bearings in said cap and the opposite end of the housing, blades radiating from said shaft and enclosed by the casing, the casing having inlet ports therein disposed to direct the pressure fluid against the sides of the respeetive blades, and the outer end of the shaft having tool-attaching means thereon.

5 A device of the character described including a housing, one end of which is pro vided with outlet ports, a casing within the housing which surrounds said ports and one end of which is fixed to the corresponding end of the housing and whose other end is free, the free portion of said casing being spaced from the housing to form a pressure chamber between them, a removable cap closing the free end of the casing, a shaft having bearings in said cap and the opposite end of the housing, blades radiating from said shaft and enclosed bv the casing, the casing having inlet ports therein dis- DOSOCl to direct the pressure fluid against the sides of the respective blades the outer end of the shaft having tool-attaching means thereon and a pipe entering said chamber and to which the housing is attached, said pipe forming means for manipulating the device.

In testimony whereof I have signed my name to this specification.
